HC-06 Bluetooth module with arduino.

Hi there! This is a short document/code to remind me what I have done with a HC-06 Bluetooth module and an arduino as it's not easy to collect the information I got here, it took me sometime.
Firstly, the module can be AT controlled and set some of the parameters as long as it's not paired with a device, so, we must first set the parameters and only afterwards play with devices. The password/pin of the device and name are not lost upon power off.
The AT available commands are:
- AT -> OK (shows status) 
- AT+VERSION -> OKlinvorV1.8 (shows firmware version)
- AT+NAMEARDUINO -> OKsetname (sets broadcast name to 'ARDUINO', kept after powerdown)
- AT+PIN1303 -> OKsetPIN (sets PIN to '1303', kept after powerdown)
- AT+BAUD4 -> OK9600 (sets the baudrate @9600,
   1---------1200
   2---------2400
   3---------4800
   4---------9600
   5---------19200
   6---------38400
   7---------57600
   8---------115200 ) 

Now, knowing this, let's PLAY!! ;)

// HC-06 Possible commands, HC-05 are different!
// ATTENTION!!! THESE COMMANDS WORK ONLY IF THE BLUETOOH IS
// NOT PAIRED WITH ANY DEVICE:
// «AT Mode: Before paired, it is at AT mode.
// After paired it’s at transparent communication.»
// (case sensitive commands)
// AT -> OK (shows status)
// AT+VERSION -> OKlinvorV1.8 (shows firmware version)
// AT+NAMEARDUINO -> OKsetname (sets broadcast name to
//   'ARDUINO', kept after powerdown)
// AT+PIN1303 -> OKsetPIN (sets PIN to '1303', kept
//   after powerdown)
// AT+BAUD4 -> OK9600 (sets the baudrate @9600,
//   1---------1200
//   2---------2400
//   3---------4800
//   4---------9600
//   5---------19200
//   6---------38400
//   7---------57600
//   8---------115200 )

#include <SoftwareSerial.h>

SoftwareSerial BTSerial(10, 11); // RX, TX

void setup() 
{
  // Open serial communications and wait for port to open:
  Serial.begin(9600);
  BTSerial.begin(9600);
  Serial.println("Enter your AT command:");
}

void loop() // run over and over
{
  if (BTSerial.available())
    Serial.write(BTSerial.read());
  if (Serial.available())
    BTSerial.write(Serial.read());
}
